What gestures are available on the regular Macbook? I don't have one yet but I like the multi-touch features on the Macbook Pro, especially the two-finger scrolling since scrolling up and down is something I do probably 8000 times a day when reading webpages and all that and I hate using the scrollbar on the right side of the screen or the down button on the keyboard. Can you do that with the trackpad on the normal Macbook? What other gestures can you do on the MB?
